POWER-TRANSMITTING MECHANISM.

Specification of Letters Patent.

Patented. June 2 7, 1916.

Application filed August 1, 1914. Serial No. 854,514.

To all whom it may concern Be it known that I, CLARENCE B. WIL- LIAMS, a citizen of the United States, re-

siding at Pence, in the Province of Saskatchewan, Canada, have invented new and useful Improvements in- Power-Transmitting Mechanism, of which the following is a specification.

This invention relates to power mechanism involving both power generation and motion conversion for general application as a means for increasing the given power of asteadily running prime motor relatively to a shaft or axle through the medium of a particular arrangement of sprocket wheels and chain belts to which the prime motor is connected and serves as the initial opera ting means, lever means being interposed between the driven element, such as a shaft, axle, rod or piston, and the chain belts and in some instances having a structure to compensate for the movement of the chain belts as they turn over or traverse the sprocket wheels over which they are trainedand also the different distances the portions of the chain belts assume in their rangeof movement relatively to the driven shaft, axle, rod or piston. The chain belts are disposed in pairs in parallel relation with a clear intervening space between them and uniformly operated without the introduction of toothed gearing between them as aunifying movement means and thereby entirely eliminate friction and lost motion incident to toothed gearing. The improved mechanism also embodies novel forms of adjustment so that various applications thereof may be accomplished with material advantages and the stroke of the interposed transmission devices modified as may be desired or found necessary.

Other advantages will be hereinafter specified, together with the construction and arrangement of parts involving the particular features of the invention.

In the drawings Figure 1 is a side elevation of a mechanism embodying the features of the invention. Fig. 2 is a top plan View of the same. Fig. 3 is a transverse vertical section taken in the plane of the line 3-3,

Figs. 10 and llare perspective views show- 111g GSSQIltll-l features of the invention in two different forms of application.

A The numeral 5 designates a base which, as'shown by Figs. 1, 2 and 3, ispreferably rectangular in shape and comprises suitable end and side bars6 and 7 which :maybe'of any dimensions adapted for the purpose of forming a rigid and stable base for supporting the mechanism. At a-suitable distance fromone end of the base, cross-supports 8 are located, and thereon is a prime motor.

9 of any preferred form having a drive shaft 10 carrying a pulley 11. At a distance from the cross-supports 8 and adjacent to one end of the base'areuprights 12, suit-;

ably braced as at 13, andhaving bearing devices 14: secured at their upper extremities for a power receiv-ingshaft 15 provided in the present instance with a pair of ratchet wheels 16, preferably near opposite extremities of the shaft 15, and also with an intermediate pulley 17 from which power may be taken by a belt 18 to any suitable point. Near the opposite end of the base are uprights 19 which havea fulcrum support on bearing castings 20 secured to the inner portions of the side bars or members 7 of the base, the uprights 19 depending slightlybelow the side bars, as clearly-shown by Figs. 1 and 3. The upper ends of the uprights 19 have outwardly projecting overhanging seats 21 to receive arcuate guides 22 of semicircular form and fixed at their ends to the side bars or members 7 of the base. The arcuate guides 22' are.

formedwith a plurality of openings 23 and adapted to receive the bolts or securing :devices 24: carried by the upper ends or.

seats 21 of the uprights 19 and whereby the entire structure, including the uprights 19 may be adjusted between the guides 22 for a purpose which will be hereinafter explained. J ournaled in the bearing castings or bearing brackets 20 is a shaft 25 constituting a motion transmitting shaft and having thereon a pulley 26 over which and the pulley 11 of the prime motor 9 abelt 27 isv -trained. Adjacent to each upright 19 and inside of thelatter are vertical supports 28 and 29 spaced apart a suitable distance and brace 30. The upper ends of the vertical supports 28 and 29 are securedto a cross or cap bar 81 which extends over and bears at opposite ends on the upper ends or seats 21 of the uprights 24. The vertical supports 28 and 29 constitute carriers forthe motion conversion elements that also assist in the increase of power relatively to the maximum power of the prime motor 9. The

two outer supports or "carriers 28 are heavier or thicker than the two inner supports or carriers 29, and both sets of carriers have upper longitudinal slots and 33 of considerable' length respectively formed therein, one in each carrier, and the lower portions of the carriers 28 have narrower longitudinal slots 34 e'\ 'tending'"therethrough in planes at right angles tothe slots 32 above. In the slots 32 and 33 sl'iiitable' "bearing members or blocks 35 'an'd'36' are mounted "and have flanged ends 37' engaged by bolts 38 which are adapted to engage openings 39 in the sideportionsof the said carriers for the purpose oiadj'ustment of said members or blocks to ch'ange"the stroke of the mechanism, all as clearly shown by Figs. 4, 5 and 6; The bearing members or blocks 35 are larger than the members or "blocks 36'and each has a short shaft 40 extending theret'hrough having sprocket wheels 41 and 42 of similar dimensions on opposite ends thereof. Extendingthrough each support or carrier 28 near the upper terminal orend wall of the lower slot 34 thereof is a shaft 43 also having sprocket wheels 44 and 45 on opposite ends thereof of sim'ilar dimensions and also duplicates in di'm'ensions of the sprocket wheels 41'a'nd"42,'and

trained 'overthe sprocket wheels 41' and 44 is a chain belt 46, and trained over the sprocket wheel's-42 and 45 is a chain belt 47. On the shaft 43 within the 'slot'34 a sprocketwheel 48 is keyed, and in thelower portion of said slot is a sprocket wheel 49 fixed on the shaft which extends through the lower extremities of-the' carriers-28am 29 and'terminally engagesthe bearing ca'stings or brackets 20. rk chain' belt 50 operatively engages each'pair of sprdcket'wheels 49 and 48 so-that 'the' pairs of chain'belts 46 and 47 at each side are regularly and uniformly driven from the motor 9 through the medium of the shaft acting as the motion intermediary or motion trz'rnslnitting means.

The chain belts 46 operate to steadyand unify the movement of the inner "chain belts 47 by assisting in maintaining a true runningoper'atlon of the shait's 40 and 43w1th less wear on the bearing means for/said shafts. The bearing'member's or blocks 36 are adjustable vertically "similarly to the bearing members or blocks 35 ,arid mounted eiatively connecting the and 60 so that the shaft 54 is directly driven from the shaft 25 at the same rate of speed.

"scribed.

to rotate in the said blocks 36 is a crossshaft 51 having sprocket wheels and onth'e'op'posite 'ends, of'the same dimensions as the sprocket wheels 41 and 42 and in transverse alinement with relation to the inner sprocket wheels 42. A second crossshaft 54 is mounted in the lower portion of the "supports or carriers 29 and has sprocket wheels 55 and 56 on the opposite ends thereof, of the same dimensions as the sprocket wheels 43 and 45 and in transverse alinem'ent with 'thednner sprocket wheels Chain belts 57 and 58 are trained over the sprocket wheels and 55 and 53 and 56 respectively, the said chain belts being separated'from the adjacent belts 47 for the connection to the belts 47 and 58 of the device or devices to be operated thereby and permit free movement of the said device or devices between these belts. The shaft 54 at an in termedi'ate point has a sprocket wheel 59 keyed thereon, and directly below and in alinement therewith a sprocket wheel 60 is secured on the shaft 25, a chain belt 61 opsprocket wheels 5!) as the sprocket wheels 48 and chain belts 50 which rotate the sprocket wheels 49 and the shafts 43 to give a similar timed operation to the sprocket wheels 44, 45, 41 and 42 through the medium of the chain belts 46 and 47. In other words, the chain belts 4'7 and 48 have a similar timed movement or actuation or run at the same rate of speed.

-'As sliown by Figs. 1, 2 and 3, two levers fo'rining'the power generating or increasing means are interposed between the shaft 15 and the chain belts 47 and 57 and 47 and 58 on the two sides of the mechanism just de- The' same operation might ensue by the use of one lever and one set of chain beltsiv'ithou't requiring any material change in the "invention, and, moreover, the number oi'lev'ers might be increased and the'chain belts correspondingly multiplied to accommodate the additional. levers. These levers 62 and 63 are formed tubular for a portion of their length, as at 64, and in'the tubular portions are telescopic or extension members 65 which are directly connected at their outer ends to and regularly follow the movement ofthe chain belts 47 and 57 and 47 and 58, the free end of each extension member 65 being connected to the chain belts 47 and 57 and 47 and 58 at one side of said belts solely or at one point in connection with each belt, as clearly shown by Figs. 6 and 7. At the points where the extension members 65 are attached to the chain belts the links 66 have inwardly projecting bosses or lugs 67 over which the opposite slotted ends 68 of a cross-pin 69 are secured by key pins connected portion of each extension member pin 69 by washers 72 fitted over the cross 1 pin and bearing against opposite sides of the extension member, the washers being held against lateral movement by pins 7 3 inserted through the cross-pin 69 and closely bearing against the outer sides of the said washers, as shown-by Figs. 6 and 7. The rear extremities of the levers 62 and 63 are formed with slots 74, one in each, and embrace the ratchet wheels 16 and also engage the shaft 15, as clearly shown, and on the rear extremities of the said levers 62 and 63 in rear of the ratchet wheels 16 and held in continual engagement with the latter are pawls or dogs 75 which are adjustable through the medium of a plurality of openings 76 in the levers, as clearly shown by Fig, 1, and whereby the strokes of the le-[ vers may be modified or the ratchet wheels changed from one dimension to another.

The actuating mechanism carrying the chain belts and sprocket wheels hereinbefore described may be adjusted or swung on the arcuate guides 22 either toward the shaft 15 to shorten the strokes of the levers 62 and 63, or away. from the said shaft 15. and past the vertical centers of the guides 22 to lengthen the, strokes of the said levers, the telescopic association of the members 65 of the main bodies of the levers 62 and 63 readily accommodating such adjustment, and, moreover, the strokes may be further modified as here, inbefore indicated by shifting the bearing blocks 35 and 36 in their respective slots 32 and 33 of the supports or carriers 28 and 29, and when these bearing blocks are shifted, shorter chain belts will be used in connection with the sprocket wheels. The extension members 65 are primarily attached in re verse positions relatively to, the chain belts 47 and 57 and 47 and 58, so that when one lever is up the other is down, and by this means an alternate stroke to the levers is given by the mechanism for operating the same, and as these-levers reciprocate, the

pawls or dogs 75 alternately grip and slip over their ratchet wheels and regularly rotate the shaft 15 with increased power proportionate to the lengths of the levers 62 and 63 and at the same time a motion conversion is effected through the operation ofthe chain belts by the prime motor 9 to operate the levers 62 and 63 as desired to perform their function relatively to the shaft 15.

In Fig. 9 practically the same principle is involved for reciprocating a lever horizontally, and in this instance the chain belts and sprocket wheels are adjusted on the arcuate guides 22 so as to assume a full horizontal position, the chain belts, sprocket wheels and prime motor and its connections being indicated by similar reference characters, as in Figs. 1 to 8 inclusive, it being understood that precisely the same mechanism is used with the exception of the modification in the form of the lever which will be presently explained. The lever in this instance is designated by the reference character 77 and embodies a main member 78 which is attached to the part to be operated, such; as a pump piston or a shaft as may be desired; and pivoted to the end of said lever, as at 7 9, is a supplemental. extension lever 80 which is inter mediately bent, as at 81, and also deflected,

as at 82, adjacent to its outer extremity. The

bends or deflections of this supplemental extension 80 of the lever are provided to permit the said extension to clear the parts of the mechanism with which it might otherwise come into engagement oluring the reciprocation, and the outer extremity of this supplemental extension 80 .is secured'to the chain belts in the same'manner. as the levers hereinbefore' explained. i

In Fig. 10 essentially the same mechanism is shown applied for operating a vertical pump 83 having a piston rod8l rising there- 7 from and to which a lever 85, in all respects the equivalent of the levers heretofore described, is connected to chain belts ;correspending to the chain belts 17 and 57 or 47 and 58 respectively engaging upper and lower sprocket wheels 41 and 4A, and 12 and l5, thesprocket wheel 41 being mounted on a short shaft 4:0 having a second sprocket wheel 11* on its outer end. The sprocket wheel 42 is mountedona short shafted having asprocket wheel 42 on its outer end,

the shafts 40 and 42 being mounted in the upper. portions of the uprights 87 which in the present instance are fixed and rise from 'a-base 88. The lower sprocket wheels 44 and 45 are respectively mounted on short shafts 445 and 45 engaging bearing members or blocks in slots 86 in the uprights 87 and adjustable. .so as to accommodate various lengths of levers or. strokes of the pump piston 84 and whereby this particular application of the improved mechanism may be I used with pumps having pistons of. varying strokes and of different dimensions and elevations. The sprocket wheels 4:1 and 412 are uniformly driven from a motion transmitting shaft 89. mounted in upright bearings 90 rising from the base 88 and having a belt wheel 91 at the center thereof which is adapted to be actuated from a motor similar to that heretofore described. -On the outer ends of the shaft 89 sprocket wheels 92 and93 are keyed, and thereover and over the sprocket wheels 41 and 42 chain belts 94 and '95 are trained so thatthe chain belts 47 and 57 may be equally and regularly driven. 1 V

In Fig. 11 the same structure as shown by Fig. '10 is mainly used and designated by similar reference characters to operate an oscillating lever 96 having a slotted end-97 and mounted 'nia'hinery or to a drill rod or mechanism for actuating the latter or may be applied to any other -vertically reciprocating means.

The improved mechanism will be found exceptionally advantageous for the'purposes for which it has been devised and has a wide range of application, and it will be'under- "stood that in making various applications thereof, such changes in the "proportions 'anddimensions as well as the minor details of construction as fairly fall within the scope of the claims will be adopted at will.
